What is the measure of other 2 angles of isosceles triangle if 1 angle is 55 degree?
It depends on whether the 55 degree angle is the odd-one-out or not.
If it is, then the other two angles must be the same, and they must add up with 55 to be 180. (All angles of a triangle must add up to 180o) So we get the equation:
2x+55=180
2x=125
x=62.5
If the 55o angle is congruent with another angle, that means that there are two angles that are 55 degrees. So if we define the other angle as x, we get:
x+2(55)=180
x+110=180
x=70.
So if x is the odd one out, then the angles are 55-62.5-62.5
If x not is the odd one out, then the angles are 55-55-70
